After decades of dominance, the Big East is undergoing a seismic shift that will essentially make the conference unidentifiable, as DePaul and six other Catholic non-FBS programs will split.

DePaul, Marquette, Georgetown, Providence, Seton Hall, St. John’s and Villanova held a conference call with Big East commissioner Mike Aresco on Thursday.

A source told the Tribune that the break did not happen Thursday, adding that a potential deal “literally changes by the hour” and it’s hard to know when it will be finalized.
